lilaehine: for pc torating the jacquard cards :tor embroider!ng machines are lmown, in which the vertical and horizontal disiilacemei'its oi the index pin with respect to the pattern board are transniitted to two separate drumswhich act as abutments for the groups of perforating punches when the paper band is being periorated and which are provided with euitahle raised and depressed parts. .ln such machines it has already been proposed to cause the means for setting the inderdpin to act on the drums tl'irough a coupling which was released after the perloratiom: have-been made, so as to enable the drums to return into their initial position. \Vith such an arrangen'ient the forward feed of the carrier for the perforating puneheswith respect (to the drums has been eii ectei'l by means oi a mechanically driven shaft, which carrier also sn 'iports the paper hand, and both the forward feed of the paper hand and the reverec rotation of the drums has been etiected. from the driving shaft;

The presentinvention relates to a machine of this kind and consists in certain improvements otythe same. In the improved machine the drums are con'ipoeed of separate discs, on the peripheries oi which are recesses and which are mounted on a shaft ex tending through them so as to rotate freely thereon and are each connected to a system of lovers capable of returning the drums into the zero poaition, a pin coupling being provided on theshatt tor each drum so as to be rotatableand longitudinally slidable, which coupling may he connected to the drum or to the frame, the drum mechanism being n'iounted in the n'iiddle of the pattern board andeach coupling being rotated by a shaft lying parallel to the drum shaft and capable of being adjusted bv hand, which is also operatively connected to the means tor setting the index pin, such that alter the index pin has been set by the driving shatt ot the inecliainiem the coupling members nredisplaced with respect to the frame nd the lIKlCX pin thereby locked while the drums are released to be acted on by the lem of levers which enahles them to he returned.

Fig. 18 is a view from above of the per-.

whole arrangement the following is to be i said, 7

In the 'l a1ne 1 the pattern hoard 2 is fixed. on which the enlarged pattern is stretched. The index pin 3 which coacts with the pattern is mounted on a sliding member i which is capable of sliding on the horizontal rail 5. lhe sliding motion is imparted to it by an endless rope (chain, belt or the like) 6 which is guided over the pulleys 7 and 8. The pulley 8 is mounted so to rotate freely on its shaft, While the pul er 7 fixed on a square part of the shaft 9, so that it cannot turn thereon, as shown in Fig. 19. For the rest the pulleys 7 and 5% are iournalled in. the guide rail 5. The guide rail 5 is fixed at eitherend to an endless bond (chain or the like) 10 and 10.-

The stretches of theseendless bands run vertically.

The upright shaft 9 is rotated by a pair of bevel wheels 11, one bevel wheel being mounted on the lower end of the shaft 9 and the other bevel wheel on a shaft capable of being turned by hand by means of the member 12. The member 12 is mounted on the end of a shaft projecting out of the casing of the perforating machine M, a spur Wheel 13 being on the other end. This spur Wheel meshes with a spur wheel 14 on the shaft 15, on which is mounted oneof the bevel wheels 11. The shaft 15 is parallel to the pattern board and is journalled on the frame 1. This shaft is divided and bears the two coupling members 16 which are connected together by pins 17 (or pawls). From the hand-operated member 12 the index pin 3 is adjusted with respect to the horizontal component.

At the other side of the perforating machine M is a second hand-operated member 12 with which a spur wheel l l' can be acted on through a spur wheel 13. The spur Wheel 14 is mounted on the horizontal shaft 15"which is coaxial with the shaft 15' already referred to. The shaft 15* is also journallcd on the frame 1; it is also made in .two parts and carries the coupling members 16 which are capable of being connected together by pins 17 (or pawls). On the shaft 15 is fixed the pulley 18, over which the vertically running endless band 10 is guided, which also runs over a pulley 2O the said bar, in a slot in which, as shown in Fig. 19., the pattern board 2 is guided, is raised and lowered by the turning of the shaft 15, whereby the index pin adjusted as regards the vertical component.

The frame 1 consists of two rigid frames, a front frame I and a rear frame H, which are connected together by transverse struts 2 1. These struts 24 are pivotally attached art-2 1 to the front frame I and are pivotally and releasably attached by screws at 25,

to the rear frame If, so that, after releasmg the screws the two parts of the frame and the transverse struts 24 can be laid fiat against one another.

The spur wheels 14 and 14L which are mounted opposite one another on the shafts 15 and 15, as is shown in Figs. 1a, 18 and 20, engage through the rear wall 26 of the casing of the perforating machine M into the said perforating machine, meshing directly with spur wheels on the shafts of the drums, the shafts of the drums not being shown. The paper band l3 which is to bc perforated is passed through the perforating machine in a direction perpendicular to the surface of the pattern board.

The index pin is; adjusted by the hand operated members 12 and 132, which at the same time set the drums. the arrangement I such that the pcrs operating the .no can accurately 'lollow the position he index pin. filter the couplings 16,

.161! disengaged. the index pin may however be adjm-eted by hand (for the purpos of returning the index to the initial.

post in or the like), without the driving mocha an of the perforating machine being acted on so as to alter the setting of the drums. The perforating machine is driven in a known .ianner from the shaft :26 which is parallel to the pattern board, so as to bring about at each revolution of thc shaft, which commences after the drums have bccn sct. the per fora ion of he cards, after which the drums turn back automatically into the initial position, during which back ard roon the drums are automatically discn a -god from the spur whccls 11 and let. In any case the person operating the machine can at any time check the perforating of the paper b. d B from where he stands.

"5 I, .Lne ielalne arrangement ol peiloiating machine and pattern board enables a checking embroidery machine S to be connected directly to the pertl'orating machine M. as is shown in 20 and 21.. the arrangement being such that the main shaft 527 is parallel to and immediately in front of the pattern board and is driven by spur gearing 28, 29 from the shaft 26 of the driving machine.

The cmbroidcring frame 30 lies in a horizontal plane (being therefore at right angles to the surface of the pattern board 2) and always visible to the person operating; the machine from where he stands. This cmln'oideringjg frame is provided with a guide bar 31. having arnr and il at right angles to one another, which the :zrzn

1" or parallel to the pattern board and lhc arm :13 perpendicular to the surface of the pattern board. The arm 23?) is cmbrzu'cd b a sliding collar 34c fixed on the end of a rack -35 which rack is parallel to the pattern board and is capable of being slid longitmlinally in the bearings 36 and 37. In enga szjcment with this rack is a pinion 38 mounted on the end of :1 horizontal shaft 39. The shaft 339 is driven by a pair of bevel wheels -10. ll. The bevel wheel 11 is mounted on a. hollow shaft which is driven by the spur wheels 43, it. from the shaft 1.3 which is parallel to the pattern board. ilhus. from the hand o;.--- erated member 12 not only the index, pin 3 and the corresponding drum of the perforatills 411g machine are set, but the. embroidering frame 30 as well, as regards one component of the StlllCll adpistment.

a shaft 1-5 parallel to the pattern board, which shaft 4? is driven through spur wheel gearing: 4-6, t? from the shalt eh) (see lire.

20) thespur wheel 48 is mounted, which meshes with a rack at). The racl: i9 is c: pable ot sliding in bearings 50 and 51 at right anglesto the pattern board. 2. it has fixed to it a collar 52 which slides on the arm 32 ot the bar 31 ot the emln'oidering frame 30. thus, by means of the hand operated member 12 not only the index pin and thecorresponding drum of the perforating machine,but also the embroidering frame 30 is acted on as regards the other component of the stitch adjustment. It should be noted that the driving wheels ate and l-l on the shafts 15 and 15 are behind the couplings l6 andlti, such that a displacement of the embroideriup; frame 30 always takes place with the displacement of the index pin, 11'- respective of whether the means for setting the index pm are connected to the pcriorah ing machine or not. i y

The vertic: l and horizontal displacements of the index pin withrespect to the pattern board are eti'ected in the manner described by means of the hand wheels 12 and 1:2, through the intermediate wheels 13 and l t or 13 and fi l driving. the shafts 15 or 15.

respectively, by which sha'lts the index pin is controlled.

It will be seen from Figs. 1 toil that the spur wheels lit and 14 mesh with the spur wheels 53 and 53 which latter spur wheels are mounted between the pin discs iii: and 55 or M and 55 res 'iectivelyconnected to them on the shafts 56 and 56 of the drums57 and 538. so as to becapahle of rotating ireetv and slidin thereon. The spur wheels 53 and 53 are ot SIP-.lllClGllt width to allow of time sliding motion, so that the spur wheels 14 and Lt alwaysremain in ene'zurement with the spur wheels 53w1nil53. The discs M and and the discs 54- and 55 are provided on their sides facing away from one another with concentric ring of pins 59 l and 59 and and 60" respectively; 'lhe pins 59 and 59 are intended to engage in the rii'ie's of holes in discs (31 and til, which discs are lined to the frame, while the pins (50 and 60" are intended for coac Kin with rings of holes in the discs 62 and; 62. which discs are fixed to the drums 5'? and Thus, when the pins (30 and. 60 engage in the holes in the discs (32 and (32. the index pin is coupled to the drums 5? and 58, so that the .rotati on oil the handwheels and 12 which iihen, however, the pins 59 and 59 are caused to engage with the fixed discs 61 and the intermediate gears 13 and 1st, 13 and 14 I respectively are fixed, so that no displace- Through the hollow shaft 4L2 there extends pins 59 and 60 are made so long that the coupling members (consisting oi the spur wheels 53 and 53 with the discs Del and 55 or 54; and 55*) are never entirely disenna ed, butt-hat the pins remain in euga 'emeut with the correspoiulingperlprated disc until the other pins have entered the other perforated disc. coupling; members can take place.

Ti lie longitudinal displacement of the coupling members is ellected by means of hell cranks 63 and (53, which are pivoted on pins (34 and 6st lined in the frame. At 65 an d. 65 the bell cranks are pivoted to slide blocks (26 and {36 which are capable 0t sliding 'i'recly between the pin d 1 .El; and and 54; and 55 respectively. The other ends of the hell cranks are each connected by a uni- .versal joint to a bar ('37, pins (38 and 68 on laterally extending arms out the said bar en gaging in longitudinal slots at the ends of the arms of the bell cranks 63 and 63. The end 69 of the bar (3'7 is longitudinally slidazble in a movable hearing, while the other end oi the bar pivotally connected to the arm T0 of a bell crank which rocks on the lifted shaft 71, the other arm 72 being: provided with a roller 73 which engages in the cam slot 7 L on one side of a cam disc 75 mounted on the driving shaft 26. Thus, the cam slot it inuparts a reciprocating or swinging motion to the bar (37, which motion rocks the hell cranks and 63, whereby the setting of the coupling members carryii'ig the driving wheels 53 and 53 is effected.

On the other side of the cam disc 75 is a cam groove 76 in which a roller 77 on the and of a lever 78 engages, which lever is lined on the shaft 79; On this shaft is also thus raised and Thus, no rotation of the Ill;

lowered by the rocking motion of thelevers i 78 and 80, i. e. ismoved with respect to the drums 57 and 58 so that therelatively stepped and sta r d ends 82) andSEi of the punches i-ft and as which are mounted in the carrier 82 so as to he loi'igitudinally displaceable in a known manner are moved towards the drums, where they either entrag c with the riders or depressioi'is on the periphery of the drruns. The carrier 82 is provided in a. known manner with a slot 555 for the passage of the paper band B to be perforated. On the carrier 82 are also provided the pins 86 and 86 which coact with on a pin 1 01 fixed to the frame.

end of the lever 18 pivoted to a sh ding memv teeth fixed on the drums 57 and 58. These teeth are provided on the edge of the perforatied discs 62 and 62 The pins 86 and 865 which are capableof sliding in the punch zarrierSiZ and are sprin loaded are so arranged with respect to t e punches 88 and 83 that-the pins and 80* engage in the rings 88 and 88. The object of the pins 80 and 86 which engage in the rings of teeth on thediscs 02 and 62 is to etfeCt the fine adfustment of the drums 57 ant 58, after they have been coarsely adjusted by the hand wheels 12 and 12 -Obvionsly it is of importance that the drums should be accurately adjusted to the size of stitch, so that the point of the index pin shall point exactly to the particular point of the pattern and that the punches shall punch the paper band exactly at the required point.

1n the cam groove 76 there also engages a i'olxler 89 mounted on the end of one arm of :a bell crank 90 pivoted on a pin 91 fixed to the frame The end of the other arm of the bell crank 90 is attached to a push bar 92, the other end of which bar is attached to one arm of atwo-armed lever 03, the end of the other arm of which is a pawl 94 of a pawl and ratchet mechanism, the ratchet Wheel 95 for which is fixedon the shaft 96. 611 the shaftv 96 are also mounted the pin drums'97, the pins of which engage in the marginal perforations of the paper band, which marginal perforations are continuously produced by punches 98 and 98" which are fixed and therefore are always in the op crative position. Thus, the cam groove 76 produces the intermittent forward feed of the paper band B.

Arolle'r 100 at the end of a rocking lever 99 also engages in the cam groove 76 of the. ram disc 75, the rocking lever being: pivoted The other her 102. This sliding member has at its 1 other end a pin 108, by which it isguided in e slot 104 of a slotted guide 105 fixed to the frame. The sliding member 102 is also provided with a slot 106 having a profile which lies symmetrically on either side of the longitudinal centre line of the sliding member and terminating in arecess 10'? to which guiding surfaces 108 lead. There are two such sliding members 102 and 102 one for each drum.

In the profiled slot of each slide 102 and 102 a pin 109 or 109 engages, which is mounted on one side of a toothed wheel 11:0 and 110 These toothed wheels mesh with spur wheels 111 and 111 rwpcrtircly, which are mounted on the drums 57 and 58. Thus, the rotations of the drums are tr: usmitted to the toothed wheels 110, 110, whereby the pins 100 and 100 are adjusted. According to whether the drums turn forward or backward (plus or minus) the pins 109, 109 more in the slot; 100, the slots in the slotted guides being so formed that, when the drums perform their maximum rotation, the pins 109, 109 will rest against the guiding surfaces 108 of the slots. For smaller rotations of the drums the pins .100, 109 remain within the range of action of the slots 105 at any point corresponding to the rotation of the drum. On the lever 00 subsequently rockingover, the sliding mcmbcru .102 are pushed until they reach the po sition shown in Fig. +1. During this motion the guiding surfaces 108 will sooner or later come in contact with the pin 100 or 105) in the symmetrical slot 100 and will forcc the pin to enter the recess, a corresponding rotary motion of the wheels .110, 110 carrynip the pins taking place, which rotary motion is transmitted to the drums. This rotary motion must in all cases be such that, when the pins rest in the recesses 10?, the initial position of the drums is restored.

Since, during the movement of the sliding members, which is very rapid, there a considerable acceleration of the masses and the drum may be easily turned too far, so that the pin 109, 105) will at fir t oscillatev between the two guiding surfaces 108, safety means are provided such shown in Fig. 5. These means consist of a bell crank .112 pivoted so as to rock about the pin 113 tired to the frame and having at the end of one of its arms a pin 11% which is capable of on gaging in anotch 115 on the periphery of a disc 116. The disc 116 is connected to the toothed wheel 110. To the end of the other arm of the bell crank 112 a tcn-ion spring; 117 is atached, the other end of which is fixed to the sliding member 102. 11011 the sliding member is in the position indicated by broken lines in Fig. 5, (which corresponds to that shown in Fig. 3) the spring 117 will pull the bell crank 112 into the position indicated by broken lines, in which the pin 114 is out of engagement with the notch 115; On the sliding); member moving: into the position shown by full lines in l ip 5 (which position corresponds to that shown in Fig, 1:) the point of attachment of the spring on the sliding member 102 paste the pivotal point 113 of the bell crank 112, so that the tension of the spring 11? tends to cause the pin 114 to engage in the notch 115 of the disc 116, thus locking the parts, so

that shortly prior-to the pin 109 entering the recess 107 the drums will have been secured against turning too tar.

, The device operates in the toll-owing mannerz, y

lVhen the coupling members 53 and 53 are in the position shownin Figs. 1 and 2, the drums 57 and 58 are set by the hand wheels 12 and 12 in accordance with the position of the index pin. ll henthis has been done, the driving shalt '25 will commence to rotate. 'lhisiotary motion in the lirst place causes the punch carrier 82 to be raised, the usting teeth till and 86 com ing in contact with the teeth on the discs 52 and 62, thus elliectiug the line adjustment of the drurns57 and 5h. 'lhereupon the ends 83 and 83 ol' the punches engage with the drumdiscs 8'7, at, so that the paper band 1% which has. also been raisedmis pertorated. "lhereupon the controlling lever oi the punch carrier rocks hacli, while the coi'itrolling levers oi the couplings are put in motion by the cam disc, so that the coupling inen'ibers carrying the spur wheels and 53 are pushed aside until the pins 59 and 59 enter into engagement with the perforations inthe discs hi and hi on the traine of the machine. The drums 5'!" am are thus uncoupled from the index; pin. oi the pattern board and can he returned into their initial position, which is el'ij'ecl'ed by the gear "for operating the sliding member 102 being put in motion by the cam disc 75. this period no movement oil? the index. pin can take place, as it is absolutely locked by the engagement of the pins 59 and 59 in the stationary discs (3.], and (31. The sliding member 102 together with the pins 109 and 1.09" returns the drums 5'? and 58 into their initial position. As soon as this has taken place, the sliding member itself returns into its initial position and the coupling parts, which are the spur wheels 53 and 51-3, are brought back into the position shown in Figs. 1 and 2, the pins (30 and '50 by engaging in the holes in the drum di. (32 and. 62 effecting the line adjustment of the drums 57 and 58. While these operatioiis are taking place, the operating gear til) to 93 tor-[the feed mechanism :lor the paperband is also put in motion by the cam disc 75 so that the paper band. is ted forward.

After one revolution of the driving shaft 26 all these operations are completed, so that thecycle of (lPQ'ltLljlOl'lS can recon'nnence.

Each component of the motion of the index pin 0 is transmitted by suitable means to the drums 57 and 58. The drum 57 is provided for thehorizontal and the drum 58 for the vertical component. The drums are mounted so as to rotate freely on the shaft 56 and are rigidly connected to the spur wheels 53 and 53 respectively. The rotary motion is imparted to the drmns from During whole is drawn together by the nuts 122 on the bolts 121, so that a rigid unit is formed.

The discs are provided with recesses 123 stamped out of their periphery, the distance rings 88 being so dimensioned that the stamped out portion of the discs projccts beyond the distance rings. Each two adjacent discs represent the plus and minus values. The discs themselves as regards their stamped out recesses correspond to the terms o'l a priigression and have a plus and minus side. in the example shown in the drawing the arrangement. is based on the geometrical progression having the terms 1, s, a, at.

The discs allow oil the material between the se nlrate connected stitch values being entirely removed, 1. e. of the formation of a common perforation, by which means the pitch :lroni stitch value to stitch value may he kept very small.

The discs which belong together lt'orthe plus and minus" values have similar rec sses, but theserecesses must be otlj'set with respect to one another in the drum. Thus, these discs may be stamped out together. llwo such discs are superposed one on the other in Fig. 10, one being partially broken away. In order that, when the discs are mounted on the dru1n,the two discs may be readily put together correctly, the holes 120 for the bolts 121 are so arranged, that they term the points of an isosceles triangle, this trianglebeingso placed on the disc that it is only necessary to turn the disc through 120 for bringing the stamped out recesses into the correct relative posit-ion, when the bolt holes 120 are brought into register. The punches d4; coact with the recesses and teeth on the discs. Two groups of punches, one for each drum are arranged in a known manner on a carrier 82 commonto the two groups, which carrier is supported by the guide bars 124, 12 i and is capable of being n'ioved with respect to the drums. The carrier is also provided in a known manner with a slot for the passage of the intermittently forwardly lied paper band B. The

upper ends 83, 83* of the punches are reduced in diameter, in order that they can enter into the recesses in the disc, some of which are very small.

In the example shown the punches are the ends'88 of the punches engage with the discs of the drums, the sharp ends of the pins 86 sliding into a gap between two teeth, thus accurately setting the drums.

Shouldby chance one of the pointed ends of the pins 86 or 56 come against the point of a tooth on the corresponding toothed wheel 82 or 62, (as indicated in Figure 15) the fine adjustment would not be made. In order to prevent this happening, an auxiliary tooth 125 is provided on the end of a rocking lever 126 having'a roller 12? resting on the cam 75 and kept in contact with the cam by a spring 128. The swell 129 on the cam 75 pushes the lever 176 towards the teeth on the disc 62, which causes a slight rotation of the drum, whereupon the lever 12 6 imn'iediately rocks back into its normal position. This slight rotation of the drum suliices for allowing the pin 86 to slip into a gap between the teeth under the pres sure of the spring 130 wound on the pin 86, the said spring having. been compressed by the pin 86 coming against the point of a tooth on the toothed wheel 62. Thus, the action of the auxiliary tooth 1.25 is to ensure the toothed wheel 62 being brought into the positions shown in Figs. 13 and 14:.
